China Manufacturer Customized Arc Motor Magnet
Arc magnets are named by their special shape ，they are also named Arc motor magnets because most arc magnets are used in electric motors or generators .Due to the technical limitation in manufacturing radially magnetized ring magnets ,individual arc magnets remains a reasonable and cost-effective option.
Arc-shaped magnets often used in different electric motors or generators. Due to their south and north polarities, they are used in torque couplings as well. Arc-shaped magnets are still the most common shape for motor magnets, especially for DC motors and magnetic rotors.
How To Buy Arc Motor Magnet ？
Size of the Arc magnet has an important effect on the performance of the motor. The following are some general effects of size parameters on motor performance:
1. Length of arc magnet: The length of the magnet can affect the magnetic field strength and magnetic flux of the motor. Longer magnets can provide a larger magnetic field, which increases the output power and torque of the motor.
2. Width of arc magnet: The width of the magnet also affects the strength and flux of the magnetic field. A wider magnet can provide a larger magnetic field area, thereby increasing the output power and torque of the motor.
3. Radian of arc magnet: The arc of the magnet determines the number of pole pairs and pole distance of the motor. Polar pairs refer to the number of North and South poles on a magnet, while polar distance refers to the distance between adjacent North and South poles. A larger number of pole pairs and a smaller pole distance can increase the smoothness and accuracy of the motor’s output.
4. Thickness of arc magnet: The thickness of the magnet has an impact on the magnetic field distribution and magnetic resistance of the motor. Thicker magnets can provide greater magnetic field depth, thereby increasing the magnetic field stability and efficiency of the motor.
For different types of motors (such as DC motors, AC synchronous motors, stepper motors, etc.), different size parameters may have different effects. Therefore, when designing motors, it is necessary to comprehensively consider multiple factors and conduct detailed design and optimization to achieve the required performance requirements.
Applications of Arc Motor Magnet
A neodymium magnets strength with no letter after the grade, i.e. N38, or N45, or N52, would indicate that it has the ability to work in an environment that has a maximum operating temperature no greater than 80C. A magnet with an “M” (i.e. N35M, N42M, etc.) generally means that a magnet can be used in an operating environment up to 100C.
An “H” material is good up to 120C, “SH” up to 150C, “UH” up to 180C, “EH” up to 200C, and a “TH” up to 220C. Again, these are general specifications and other factors do play a role in coercivity decisions.
Why Choose Pufeite As Neodymium Arc Motor Magnets Manufacture
We want to bring our knowledge and experience to the forefront by actively participating in your upcoming projects. Work with our magnet experts to get the right magnet solution.
Application of Neodymium Arc Magnet
Almost all of Neodymium arc magnet is used for both rotor and stator in permanent magnet motors ,generators ,magnetic coupling machine.
Pufeite mangetic manufactures arc motor magnets made of Ndfeb magnet ,Smco magnet and hard ferrite magnet for a variety of motor demands .we alos supprot R&D projects of motor manufacture by quickly magents samples.
Reduced Air Gap: The curved shape of arc magnets allows them to bring the magnetic field closer to the stator. This reduction in the air gap between the magnet and the stator contributes to increased magnetic efficiency and improved overall motor performance.

Magnetization Direction of Arc Magnets
Magnetization direction is a very important factor. Arc magnets have various magnetization directions: diameter direction, radiation direction, and thickness direction. Different magnetization directions make the magnet have different magnet performance. If you get it wrong, the magnet produced is also worthless, so customers should pay attention to this point.
Optimized performance and cost with Ndfeb magnets
Cost considerations are usually part of the discussion. As a general rule, the higher the grade, the higher the price. There are other variables, including shape and size, but for this purpose, we will use the general rule of higher grade = higher price. And, along with this rule, the higher the letter after the grade, the higher the price. So, for example, an N48H will cost a bit more than an N48. And an N48SH will cost more than an N48H, and so on. And finally, even a lower grade material can cost more than a higher grade material if a higher letter is selected. For example, an N35SH will most likely cost more than an N38 or even an N40.
